About AlertaParques

AlertaParques is, for now, an informational and transparent weather tool that builds evidence over time.

What AlertaParques is and is not

Informational

Trail-level weather information to prepare a trip: what to bring, what to watch, when to hesitate. It never tells anyone it is safe to go.

Transparent

Each estimate shows where it comes from (model, time, point and its elevation), how much confidence it deserves and its limits. Known errors are published.

Building evidence

Since 2026-07-02, every estimate is logged to compare it with what actually happened. With that evidence we will adjust thresholds and seek professional validation.

What AlertaParques is not

  • It is not an official warning system and does not replace CONAF, SENAPRED, SERNAGEOMIN or the Chilean Meteorological Office.
  • Its thresholds have not yet been validated by a meteorologist.
  • It does not see the ground: ice, crevasses, floods or closures announced only at the ranger station.

Why it exists

The project was born after a tragedy in a Chilean national park in 2025. Looking at existing tools, we did not find one that brought together, for each trail in Chile’s national parks, weather estimates, their limits and official notices in one place. Useful sources exist — the Chilean Meteorological Office, CONAF, SENAPRED, global apps like Windy or Meteoblue — and AlertaParques tries to bring them closer to people preparing a trip, without replacing them.

What it does today

  • Estimates every hour the level of 82 trails in 57 national parks, using wind, gusts, rain, snow, temperature and visibility from Open-Meteo.
  • Uses different rules by terrain (trail, mountain range, volcano, altiplano), because one threshold does not fit all.
  • On volcanoes and altiplano it compares three models (best_match, GFS and ICON) to show how much they agree, and publishes each estimate’s confidence.
  • Shows SERNAGEOMIN’s volcanic technical alert and the closures CONAF publishes in its RSS feed.
  • Has a public read-only API. API

How an estimate is produced

1 Weather data Open-Meteo · best_match · GFS · ICON Hourly query · GFS/ICON only on volcano and altiplano 2 Terrain classification trail · volcano · highland · altiplano Criteria adapted per route type 3 Rules by terrain Tailored thresholds · confidence level best_match decides · GFS/ICON only compare 4 Estimated level No alert Caution Danger Per trail · informational Updated every hour

How you can help

  • Meteorologists and meteorology students: review the thresholds and how to verify them.
  • Park rangers, Socorro Andino and mountain guides: tell us real conditions and when the estimate did not match what they saw.
  • Anyone who has been on the ground: send us the park, trail, date, time and what they observed. Every report adds evidence.

Responsible use

Weather models work with estimates, not certainties, and mountain weather can change abruptly. Use AlertaParques together with official sources — CONAF, SENAPRED, Chilean Meteorological Office — and with what park rangers and guides tell you. In a risky situation on the ground, your own judgement and local authorities’ instructions come first.

Goals

  • Remain free, ad-free and open.
  • Gather enough evidence to publish hit rates by terrain type.
  • Obtain a professional review of the thresholds.
  • Explore funding without turning the site into a commercial product.
